Q
Is it really true that ADSORB-AT-NITE won't adsorb water?
A
If ADSORB-AT-NITE granules are left in water over extended periods of time, only but a small amount of granules will sink. ADSORB-AT-NITE FENCE OR MATS will stay afloat for two to three months. In the event of an oil spill, it is crucial for booms and mats to remain deployed on the water surface over extended periods of time (typically between 3-5 days) to ensure oil containment. As a general rule, booms and mats are not deployed for longer than a month. Therefore, in response to the original question, ADSORB-AT-NITE will not sink.
Actual performance records indicate that oil-saturated ADSORB-AT-NITE MATS remained buoyant within an oil trap for over a year. Go back
Q
Isn't ADSORB-AT-NITE ACTIVE CHARCOAL toxic?
A
SUMILEI is a positively safe product! SUMILEI is manufactured from the steam-activated extract residue of canned coffee. Go back
Q
Does ADSORB-AT-NITE adsorb odors?
A
ADSORB-AT-NITE will adsorb certain odors.The specifics of what Active Charcoal is to adsorb are determined at the time of manufacture.There are different types of active charcoal specializing in the adsorption of vapors only, nitrogen only, carbon gases only and so on.Since the objective of ADSORB-AT-NITE is to adsorb oil exclusively, emphasis is not on odor adsorption, although ADSORB-AT-NITE does adsorb oil odors Go back
Q
Does ADSORB-AT-NITE burn easily?
A
Charcoal (carbon) is a substance that does not burn easily. When a golf club shaft made of carbon is exposed to fire, it will not burn.ADSORB-AT-NITE is difficult to ignite. When ADSORB-AT-NITE is deployed on top of burning oil, it will, in fact as a fire-extinguishing agent. Go back
Q
Does ADSORB-AT-NITE adsorb cooking oil?
A
Yes. ADSORB-AT-NITE adsorbs cooking oil.ADSORB-AT-NITE will not adsorb animal fats that solidify at low temperatures. However, ADSORB-AT-NITE will adsorb hot, liquefied animal fats. ADSORB-AT-NITE placed in triangular kitchen waste disposals will prevent oil from draining into drainage pipes. Go back
Q
There are two different types of ADSORB-AT-NITE OIL MAT, Type B and C. How do they differ?
A
Both products are filled with ADSORB-AT-NITE. ADSORB-AT-NITE is the actual oil adsorbent. What differs is the outer cover. Type B is covered in covered with cotton fiber. The outer shell of Type C is made of non-woven material manufactured from polyethylene and polyester (PET: polyethlene terephthalate). Use Type B for deployment on water for two to three days. For longer deployment, use Type C, which will not deteriorate. Go back
Q
In the catalog, the size of ADSORB-AT-NITE pores is given in um. Exactly how big is that?
A
'um' refers to micrometer. um equals one thousandth of 1mm. For your reference, please consult the following chart.

Q
How should I dispose of oil-saturated ADSORB-AT-NITE products?
A
Dispose as industrial waste. Small quantities will be picked up as household garbage. Please check with your local waste disposal office for more information. Go back
Q
Will oil slicks on water completely disappear after deployment of neutralizing agents?
A
Cf. 'neutralizing agents'.The term 'neutralizing agent' is used for oil spills on rivers in conjunction with oil booms.
'Neutralizing' generally refers to the process whereby an acid and an alkali are mixed, thereby removing their respective characteristics. In this case, however, 'neutralizing' refers to a surfactant, which binds to oil and weakens surface tension. The oil is emulsified and minute oil droplets are dispersed in water. The characteristics of the oil itself remain unchanged.
Oil Dispersants (also called neutralizing agents) cause the formation of minute oil droplets, which disperse in water and are invisible to the eye, i.e. the water appears clean.
In short, the oil is not "neutralized", which is why we encourage disuse of this misleading term.
Oil dispersants have been in use in Japan since 1956. This includes highly toxic substances and those that do not decompose well. At Taniguchi, we have developed a highly environmentally friendly oil dispersant. Still, we discourage the use of oil dispersants in rivers.

Q
Why is ADSORB-AT-NITE an effective oil adsorbent in rivers?
A
That is because this adsorbent is compatible with low viscosity oil.
The pores size of ADSORB-AT-NITE adsorbents is 1/1000-1/10,000 the diameter of conventional adsorbent pores. ADSORB-AT-NITE pores are ultra-small and have an inverse adsorption capacity of between 550 to 1000 times.
Most oils spilled on rivers have a low specific gravity, are low in viscosity and form a thin, glittering oil film on the water surface. The thickness of this oil film amounts to 1/10000 to 1/100,000mm.
Since river water is a source of water for consumption, industrial and agricultural purposes, even minute oil traces have to be removed. Only ADSORB-AT-NITE with its small pores and great adsorption capacity is able to soak up even the thinnest of oil films. ADSORB-AT-NITE is very compatible with low viscosity oils.
Small pored adsorbents such as ADSORB-AT-NITE do not work well with oil spills at sea. Oil spills at sea mostly involve highly viscous heavy oils. Viscous oils such as crude oil and type-C heavy oil have high specific gravity, which makes it difficult for adsorbents with small pores to soak up all the way.
To sum it up, Generally ADSORB-AT-NITE works well on inland waters. ADSORB-AT-NITE works at sea if the oil spill consists of low viscosity oil. Go back
Q
I think that conventional thick and heavy oil fences are better adsorbents than thin and lightweight ADSORB-AT-NITE OIL FENCES.
A
When waves hitting the front of the boom cause low viscosity oil to drain away from and flow away underneath the boom, a phenomenon known as 'entrainment' occurs. When high viscosity oil, which accumulates at the front of the oil boom flows away underneath the boom, this is commonly referred to as drainage' phenomenon.
Most oil spills on rivers involve light oil with low specific gravity and low viscosity. The entrainment phenomenon mentioned above, applies mostly to light oil. Oil outflow associated with entrainment occurs regardless of boom gauge and size. Entrainment occurs regardless of diameter and weight of the oil boom.
The outflow of oil with high viscosity and high specific gravity at sea is associated with the drainage phenomenon. Here, deployment of thick and heavy oil booms is more effective.
In rivers, however deployment of 2-3 thin oil booms is more effective than deployment of a single thick oil boom. Parallel-deployed booms increase effectiveness when lines up at distances of four times their diameter. Go back

Q
Won't AC-LITE cause clogging of water permeable (drainage high function) pavement?
A
The Guidelines for Public Works issued by the Ministry of Land and Transport stipulate that the co-efficient for the standard rate of pavement permeability must equal 1x10-2cm/s.
The permeability co-efficient of AC-LITE equals 7.1x10-3cm/s, in granule state 1x10-2cm/s and even in crushed state approximates 1x10-2cm/s, i.e. 9.2x10-4cm/s. AC-LITE does not normally contribute to pore clogging. However, if a considerable amount of oil is soaked up, there is the possibility that any adsorbent will clog. Please contact us for further information.
Co-efficient values at a glance:
Water drainage of sandy soil: 1x10-3cm/s.
Drainage of mixed sand/silt drainage: 1x10-2cm/s .
Drainage of soils, which are neither clay nor sandy: 1x10-3cm/s.
Drainage of compressed soil:1x10-4cm/s.
Drainage ofsoil compressed by heavy machinery, i.e. rainwater puddles remain even 3 days after rainfall: 1x10-5cm/s.
The permeability co-efficient 1x10-2cm/s of paved surfaces is calculated at a rate of 360mm of rain per hour. Go back
